Title: Push pull amplifier
Inventor: NAKAYAMA TAKUHIDE
IPC: H03F3/20
Filed: 1979-02-28
Abstract: PURPOSE:To reduce the variation in the output offset voltage, by feeding back the difference between the DC value at the output terminal and ground potential via the operational amplifier. CONSTITUTION:When a signal is fed to the input terminal IN, the input signal is amplified with the push pull amplifying circuit consisting of FFTQ1, Q2, driver transistors (TR)Q3, Q4, and output TRs Q5, Q6 and given to the output terminal  OUT. Since the noninverting input terminal of the operational amplifier OP is connected to the output terminal via the AC blocking filter, the offset voltate value at  the output terminal is compared with the ground potential and the compared output  is amplified and outputted at the terminal A. Accordingly, when the offset voltage of the output terminal is shifted from the ground voltage, an output is given at the terminal A, and the base bias of the output TRs Q5, Q6 is controlled via the current Miller circuit (TRs Q7, Q8, and TRs Q9, Q10) to shift the offset voltage at the output terminal to ground potential.

Abstract: PURPOSE:To obtain a high-tensile steel plate of superior homogeneity having no differences in mechanical properties between its end parts and inside by selecting steel composition of C, Si, Mn, P, S, Nb, V adequately, and specifying the water cooling conditions after correct controlled rolling. CONSTITUTION:A slab of 0.05-0.15C by weight%, 0.15-0.50 Si, 1.50-2.50 Mn, <=0.025 P, <=0.015 S, 0.02-0.05 Nb, 0.02-0.08 V, and if necessary, <=0.3 Cu, <=0.5 Ni, <=0.25 Mo and the balance Fe with unavoidable impurities is rolled at >=30% draft at Ar3 transformation point + or -50 deg.C, and the rolling is ended within  said temp. range. This steel plate is water-cooled from said temp. range down to 450 deg.C at >=2 deg.C/sec cooling rates, whereby the high-tensile steel plate of  5-50mm. thicknesses is obtained. This results in the lower temp. in the end parts  than in the inside during rolling, the higher draft of (alpha+gamma) two phase region  and the higher strength. However, in the water cooling, the opposite from the  above result, and both strengthening effects are combined, whereby the strength  differences of the steel plate are eliminated.

Title: Disk driver
Inventor: YAMASHITA YOSHIHIDE
IPC: G11B19/20
Filed: 1988-02-02
Abstract: PURPOSE:To correctly recognize respective sectors by recording an identifying signal at the leading parts of the respective sectors, generating an index signal from the part to be detected of a turn table through a delay circuit and completely separating the identifying signal. CONSTITUTION:A disk is rotated, an index detector 5 outputs the index signal and this signal is outputted to a servo ID counting circuit 8 through the delay circuit 7. The circuit 8 resets a counter by the index signal to begin to count a servo ID signal. When the index signal is outputted to the circuit 8, since a head 6 is situated at the intermediate position of the data area of the sector, the generation of the signal of the detector 5 and the generation of the servo ID signal are uneven according to various reasons, however, a generation sequence is not reversed. The respective sectors are constantly designated by the same address to correctly recognize.

Title: Ultrasonic motor
Inventor: MIYAZAWA OSAMU
IPC: H02N2/00
Filed: 1994-02-21
Abstract: PURPOSE:To obtain a high-efficiency and low-cost ultrasonic motor by a constitution wherein a rotor is flexible so as to obtain a good contact state. CONSTITUTION:A piezoelectric element 7 is attached to a disk-shaped stator 1 which has been fixed to a frame 5 by a fixing screw 10. When a voltage is applied to an electrode pattern 8 via a lead wire 8, the stator 1 is vibrated. A pinion 3 which is used to take out a turning force is fitted to a rotor 2 which comes into contact with a protrusion la on the stator 1 and which is driven frictionally by a vibrating displacement. The shaft 3a of the pinion is positioned in the transverse direction and the height direction by a receiver 6. Since the rotor 2 is flexible, it comes into contact with the protrusion part 1a on the stator. However, when the deformation amount of the rotor 2 is ensured so as to be at the height or higher of the protrusion part 1a, the rotor can obtain stable contact. Since the receiver 6 gives a pressure force, other members used to give a pressure force are not required. As a result, it is possible to obtain a low-cost ultrasonic motor whose efficiency is high.
